IMPROVEMENT IN COMBINED SASH HOLDERS AND TIGHTENERS.

Specification forming part of Letters Patent No. 132,819, dated November 5, 1872.

To all whom it may concern:

Be it known that I, AARON P. DANFIELD, of Chester city, in the county of Delaware and State of Pennsylvania, have invented a new and Improved Sash Tightener and Holder; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawing forming part of this specification, in which- Figure .1 is a perspective view, and Fig. 2 a vertical section transverse to the axis of the rubber roller.

Similar letters of reference in the accompanyin g drawing indicate the same parts.

The object of this invention is to provide for public use a simple and cheap adjustable device adapted to prevent the rattling of window sashes, and to lock them down; and to this end the invention consists in the combination of the anti-rattling and locking devices, as hereinafter described.

In the drawing, A is the window-strip, B the lower sash, and U the upper sash. M is a casting, constructed in the form of a flat plate, m, having a semi-cylindrical cap, m, attached to its face, as shown, the front edge of the cap being in line with the edge of the plate. Within this cap, and almost entirely concealed by it, is an elastic rubber roller, I, the front side of which is designed to bear against the edge of the window-sash, as represented in Fig. 2, and prevent the latter from rattling. This device would be almost worthless were it not adjustable, and, if adjusted by removing the fastening-screws and inserting them in a new place in the strip, the beauty of the latter would soon be destroyed. To obviate all difficulties I provide for the adjustment by casting the plate at withtwo transverse slots, 6 e, and fastening it to the wood by means of set-screws passing through the slots. Only one hole is thus made in the wood at each end of the plate, and the most minute adjustment can be read ily effected to counteract the slightest wearing of the sash or shrinkage of the wood. For the purpose of locking the sash down I attach to it a barbed spring-hook, h, so arranged as to catch under or over the edge of the projecting cap m, as shown invFig. 1, and thus automatically lock the sash to the casing.

The pressure required to hold large windows still in heavy'gales and to hold car-windows from rattling during the movement of the train is very considerable; and, besides, it may be desirable often to dispense with window-sprin gs and weight-balances and to employ my device for holding up the sash when raised. For these reasons I make the supporting part M in the form ofa metal casting on account of its greater strength. A plate made of two or three parts struck up and fastened together might be used, but would obviously be weak and liable to give way after short service.

Having thus described my invention, what I claim is- The locking and anti-rattlin g device herein described as an improved article of manufacture slotted casing M m and rubber roller I combined with the spring-hook h, in the manner and for the purpose set forth.
